I am researching the LYDIA, a brig of 200 tons, built of teak around 1800. I think it had a crew of around 20. (Details on the ship are in Judge Howay's "List of trading vessels in the maritime fur trade").
Not having found any drawing or diagram of it yet, I'm wondering whether another similarly-sized brig of the same era would have been substantially the same. To what degree would they have looked alike? Could LYDIA have had any unusual features or would it have been built to a well-known pattern?
